STAPLING- REYNOLDS.

MACHINE.

SPECIFICATION forming part of Letters Patent No. 253,168, dated January 31, 1882.

Application filed October 10, 1881.

T all whom it may concern:

Be it known that I, BLUKER E. MILLER, of La Fayette, in the county of Tippecanoe and State of Indiana, have invented certain new and useiul Improvements in Stapliug-llIachines; and I do hereby declare that the following is a full, clear, and exact description thereof, ref erence being had to the accompanying drawings, and to the letters of reference marked 1c thereon, which form partof this specification.

The object of this invention is to provide a machine which shall be capable of both cutting and bending wire into the rectangular staples employed as paper-fasteners, and also of driving and clinching the same, so as to fasten the sheets of paper together. These objects I attain by means of the mechanism illustrated in the drawings, in which Figures 1 and 2 are reverse side elevations of my invention; Fig. 3, a face view of the head with cap-plate removed Fig. 4, a vertical cross-section of the same; and Figs. 5, 6, 7, and 8 are detail views of parts of the same.

A indicates the base of the machine, and B 2 5 a vibratory arm that is johrnaled at one end between lugs a a upon the base-plate. The vibratory arm is provided with a head, 0, that has a vertical channel, 0, formed in it for containing the principal operative parts of the mao chine, said groove or channel being covered by a suitable cap-plate. The wire passes from a reel through a post, D, upon the bed-plate, at which point it is acted upon by a springpawl, (7, arranged to admit of the forward feed 5 and to check any back movement of the wire. This wire also passes through an opening, 0, in the side of the head upon the vibratory arm, at which point it is also acted upon by a like spring-pawl, E, which performs the same fu nctions as the pawl just described. As the arm B is raised the wire will be held by pawl d, and pushed past the pawl E into the head of said arm. As the arm is lowered the wire will be held by the pawl E and drawn past 5 pawl d, so as to provide additional length for entering the head at the next operation. The

wire enters the recessed head just over the anvil F, which is arranged in the lower part of the said head. If now the spring-plunger Gr, which reciprocates in the groove of the head,

(Model) is depressed, it will strike the wire and sever it by forcing the same against a cutting-edge,

H, at the inner end of the opening 0, through which the wire passes. The plunger is bifurcated at its lower end, and asit is still further depressed it will bend the wire into the form of a staple upon the anvil, whiclrlatter will be received between the forks of the plunger. To prevent the bent wire from now rising with the plunger when the latter is allowed to ascend, I provide a slidable check, I, consisting of a small bar having bent ends 1' 'i, and also having a screw, k, which latter passes out through aslot in thehead and engages a spring or friction plate, k, which prevents the device from moving too freely. The lower end of this check I will be just above the wire, and will hold it down. When, however, the plunger has about reached its upstroke, a pin, 6 on its lower end will strike the upper end of the check, thus raising it. As the plunger is allowed to rise the lower bifurcated end of a swinging clearer-bar, L, will move forward, so that its forks will embrace the sides of the anvil and push the bent wire olf of the same into a chan- 7 no], L, in the cap-plate. This clearer-bar is pivoted at its upper end in a smaller channel,

l, in the head, and it is formed with a slot, Z, through which the bent ends of the check-bar I project, so as to be engaged by the pin on the plunger. The clearerbar is also formed with inclines Z l on one side, so that the descending plunger, striking the same, will push the bar back into the small channel, and hence move its forked end away from the anvil, and as the plunger rises said clearer-bar will be gradually swung forward, so as to push the wire off the anvil by reason of a spring, M, acting against a pin, m, on the clearer-bar. The wire staple, being thus pushed oifthe anvil, will be forced down through an opening at the bottom of the head by means of a small auxiliary plunger or driver, N, arranged to work in the cap-plate channel and operated by the plunger. This driver forces the wire through the paper, 5 and a continuance of pressure or a sharp blow will clinch the ends of the wire, as usual. To facilitate this clinchinga bed, 1?, upon the base plate has a groove, 1), with inclined ends, so that during the above operation the ends of the Wire will be directed toward each other. During the downstroke of the plunger the clearer-bar will be pushed away from the anvil and the check-bar will be brOught down by the pin on the plunger striking the lower end of said check-bar, so as to hold another piece of wire. It is of course understood that the arm should be vibrated at the proper moment in order to feed the Wire into the head where it Will cross the anvil, and then be severed between the descending plunger and the cuttingedge before described.

What I claim is-- 1. The combination, with the anvil F, of the plunger G and the Sliding check I, substantially as described.

2. In a wire cutting and bending machine, the combination of the check I, having the bent ends i 2', with the slotted clearer-bar L and plunger G, having pin i all constructed and arranged to operate substantially as described.

3. In a wire cutting and bending machine, the combination, with a plunger and a swinging clearer-bar, of the check I, having bentends 'i i, screw-threaded pin it, and spring It, allconstructed and arranged to operate substantially as and for the purpose specified.

4. The combination of the swinging clearerbar L, formed with slot l and inclines P I, with the sliding check I, plunger G, and anvil F, all constructed and arranged to operate sub stantially as and for the purpose set forth.

5. In a wire cutting and bending machine, the combination of the clearer-bar L, plunger G, spring M, pin -m, sliding check I, and anvil F, all constructed and arranged to operate substantially as and for the purpose set forth.

6. In a wire cutting, bending, and clinching machine having a base-plate and a vibrating armhinged or pivoted thereto, the combination of the head 0, provided with a suitable anvil therein, with a bifurcated plunger, a bifurcated and swinging clearer-bar, the sliding check I, auxiliary plunger N, and plate P, having clinching grooves, all constructed and arranged to operate substantially as and for the purpose set forth.

In testimony that I claim the foregoing as my own I affix my signature in presence of two witnesses.
